CURRENT-AMPLIFIER.

To all Ic/mm it may concern.

Be it known that I, Atrous'r J. Thomson, a citizen oi the United States, residing at New York. in the county and State of New have invented new and" useful Improvenu-alts in Current-Amplitiers,of which the following is a specification.

My invention relates to amplifiers for electric currents and has for its object to provide a diagram oil' electrical circuits and generators for the purpose of amplifying oscillatory currents between signaling stations; whereby transmitted current varia-' tions are repeated and reinforced for the receiving ap mratns without a reaction of the currents upon the transmitting station apparatus.

Another object of my invention is to pro vide a repeating coi-l, which permits of senoling the entire transmitting current to another signal station, while the strength of the received currents may be varied as con venicnt.

A further object 01' my invention is to provide an electric generator without commutator, bars and oscillating poles for the purpose of generating continuous electric current, thus obviating: the detrimental cur rent variations by a sparking of the brush collectors and of frequency current generators. M

Referring to the drawing, forming a part this specification which shows my invention diagrammatically and in which like numerals of reference indicate similar parts in the view, the .nimie'rals l and 2 designate two stations, equipped for telephone service, wl'ierehy call-bells, switch-hooks and other parts are omitted as well known in the artand not necessary for a complete understandil'ig of the device. The numerals 3 and 4: denote two electrical generators, forming an amplifying relay for the oscillating current, while the numeral 5 represents repeating coils. The latter have three separate coils, otwhieh, one coil forms a circuit With a transmitter 6 and battery 7 by means of wires 8; another coil 5? of the repeating coil 5 is connected to a receiver 9 by means of wires 10, which may include a condenser 11. A diainagnetic tube 12, such as brass- IS provided movable between core 5 and the Winding 5 of the repeating coil 5,130 vary the amount of induced current in the-winding and to attain any desired loudness of the receiver. The movement of tube 12 may Specification of Letters Patent.

e accomplished with a handle 13 or with other suitable means, or it may be connected to a rod extending through the casing of the inclosed apparatus for the damping of the currents. The third coil 5 of the induction coil 5 is connected with the line wires 26 and ll to the relay station 3. The station 2 consists of similar parts, as described in connection with the first station, and the winding 5" of its induction coil 5 is connet-ted with wires 16 and 17, to the field coil 18 of generator at.

An amplifying relay is interposed between the signaling stations and embraces two current generators 3 and 4 and suitable electrical connections among the Various parts ofthc set, which permit the amplify ing at current from a transmitting to a receiving apparatus but prevent a reaction of the amplified currents upon the transmitting apparatus. For this purpose, I provide the field magnets oa an amplifying generator with. a differential coil and connect the same to the main circuit in a manner, so that the current from a transmitting apparatus surges in the same direction through the difterential coil as through the main field coil and thus energizes the generator; but an amplified current from this generator surges through a dillerential coil in the opposite direction to that in the main coil, which energizing of the amplifying generator. Thus. the transmitting apparatus 1, for instance, is connected by wires 14- and 26 to both field coils; the differential coil 15 and the main coil 19. The latter is in series with the armature or generating coil ct to amplify the electric current from the transmitting apparatus of station 2. The an'ipliiied current which is produced in coil 24 of generator 3, surges through a main coil 20 and to the receiving apparatus of station 2, and further through a differential coil 18. Itwill be seen from. the accomhat a current from an armature or an'iplifying coil surges in oppoanother generator 4, which serves.

site directions through both field coils, while 7 other station without changing any connec-' tion.

For the purpose of eliminating any detrimental pulsation in the generation of the amplified current, I employ a novel generator without collecting rings or frequency producing poles. These generators are provided with stationary field and amplifying coils, the amplifying coils of which are arranged, so as to be cut by lines of residual magnetic force of a rotating armature bobbin, which is induced in the latter through the field coils of a generator. The arrangement of the amplifying coils depend upon the capability of the armature bobbin to retain a magnetic charge. In practice, the amplifying coil may be arranged in a plane with the field magnets and at an angle with the field coils it may further be placed with its wires between the field poles, or above the same, or it may have a portion upon the field magnets.

In providing the repeating coil, the adjustment of the same may be varied by arranging the coil or core so as to be movable with respect to each other instead of the arrangement described, and in forming the generators, the same may be embodied in any convenient casing; further I may employ as many amplifier sets between two stations as desired and it will be observed that my invention is not limited to the exact form of 1, he parts herein described, and it is evident that "various changes and modifications may be made of the same without departing from the spirit of my invention.
